OF ILLIN 018.

To all nr/wI/t'it In/my concern:

Be it known that I, THOMAS R.l\/ICKN1GH'1, a citizen of the United States, residing at Aurora, in the county of Kane and State of .lllinois, have invented certain new and use ful improvements in Dump-Cars,*of which the folmwing is a specification, reference being had to the accompanying drawings.

My invention relates to dump-cars, and has particularly to do with cars arranged to he operated to dump a load or to return the ear-Lolly to its normal or-operative position by thefuse of compressed air.

The objects of my invention are to provide air operated mechanism for dumping the load at either side of the ear 'and'for restoring the car-body to its norinal or carrying position, to provide aireoperated mechanism so arranged that any car in a train may be glngnped at either side at pleasure inde train, to provide improved airoperated mechanism so arranged that the power employed in durnping the car-body or restoring it to its normal position is most advan. "gcously applied, to provide improved 111191. by which the dumping of the various carsor their restoration to carrying position. may be controlled by an opera-tor located in the engine or at any other suitable point, and in other respects to improve the construction of cars of this class. I accomplish these objects as ln'reinafter described, and as illustrated in the drawings.

What I regard as new will he set forth in the claims.

In the accompanying drawings, Figure .l is a side elevation of my improved ear. .Figs. 2, 3, and 4 are detail views illustrating dillcrent positions of the camsthrough which the i compressed air operating mechanism for dumping and returning the car-bodn-ss acts.

showing one of the cams evers of the air-cylinders are connected to said rockshaft, and Fig. 13 is a detail of one of the control]ing-valves.

In the construction illustrated each dumpcar consists of a suitable car-body pivoted centrally on a pair of trucks so as to rock or tilt toward either side of the track to dis- The car-body is provided with swinging sides constructed so that when the car-body is tipped to either side the side board at the side toward which the car-body or .elevatechso that the load can be freely discharged. lt will he um derstood that while'l prefer to en'iploy the construction shown for pivoting the car-hody upon the trucks and for operating the side hoards of the car my present invention is not restricted to such. features, as any other suitable constructioninay be employed. In fact,so far as my present invention is concerned it has nothing to do with the manner of pivoting the ear-bodyor the construction and arrangement of the parts of the car-body other than that the car-body must be capable of being tipped to either load if all the features of invention here-- inafter set forth are to be realized.

Each car may be provided with the usual air-brake mechanism, and suitable couplers and draft connections are provided. so that the several cars may be coupled in train. Each car is further provided, perl'erahly at opposite sides, with longitudinally-extending train-pipes arranged to be coupled suceessively with corresponding train piprs of tlze adjacent cars, so that when the ears are coupled to form a train thereare extending the full length of the train. 'J hese train-pipes are connected by a three-nay cock with an air-pump or other equivalent means of supplying them with compressed air,so that by operating saidr air may be supplied toeitlier of-said trainpipes alone. at the engine, which also supplies the coinhut it may be othernise. placed.

lhe two rock-shafts are connected with opposite sides of the car, so that by rocking the appropriate shaft the'car-body may be tilted in the desired direction.

lhe train-pipes which supply compressed air to the dumping mechanism are in addition to the usual air-brake train-pipe, which has nothing to do with-my present invention. For convenience and description therefore the term train-pipe without qualification,

-.as hereinafter used, refers to the train pipe or pipes which control the actuation of the dumping mechanism as distinguished from t'he air-Drake train-pipe.

Between each train-pipe and the cylinders- The connections between each rock-shaft and the operating-lever through which it is connected with the compressed-air cylinder a cam-lever fixedly secured to the comprise running over-said cam rock-shaft and a chain and connected with said lever, the arrange ment being such that when said lever is positively .actuated b'y'the admission of compressed air .to the appropriate cylinder the I chain or other flexible connection acts, in connection with said cam-lever, to rock the rock'- shaft. Similarly the rock-shaft is connected with one side edge of the car-body through chains or other flexible connections and camlevers placed near the ends of the car and so arranged that when the rock-shaft is rocked,

as above described, to tilt the car-body said latter chains are wound upon their respective cam-levers, thereby drawin the car-body down at that side into position for the discharge of its load. The various chains are so arranged as to provide slack enough so that the chains at one side'of the car do-not interfere'with the tilting of the car-body toward the-opposite side, as wilLbe hereafter more specifically described. Suitable stays or chains-are provided at each side of the car to 7 sn i-tsnormal or carrying position. The-stays the load is to be 'du rnp "fore the dumping operation, those at the other side acting to prevent the car-body going too far when returned to its carrying position.

The foregoing explanation, it is believed,

will be'suflicient-to give a general idea of the.

construction of my improved dump-car and the manner in which it is used either alone 01 in connection with other cars. I will how dethe car-body, which, 7, are connected with the ends best shown in Figs. the opposite sides of the car and extend lonthe sideogpositethat at which e aredisconnected beascribe more specifically the construction illustrated in the accompanying drauings, which illustrate one of the various forms in which my invention maybe applied.

tteferring to the drawings, 13 14 indicate trucks, and 15 the car-body. As test shown in Figs. 1 and '18, the trucks carry a num; er of sockets 16, which receive pivot-plates 17, pivotally connected by pivots 18 with suitaple Lrackets 19, secured centrally to the underside of the car-body, as shown. The arrangement is such that the car-hotly may be tilted toward either side of the truck, as indicated in 1 ig. 7.

21 22 indicate the movable side boards of as shown in Figs. 6 and of the carbody by straps 23 24, arranged to operate in connection with straps 25 26 to hold the said side hoards up and turn their lower edges outward when the car-l;ody is tilted, as shown inFig. 7. The side boards may, however, be operated in any other suitable way, and as these parts have nothing to do with. my present invention a further description thereof is helieved to be unnecessary.

27 28 indicate the upper and lower memlJers of stays which are provided at each side of the ear, preferatly near the ends thereof, and 29 indicates hooks which connect the memters of'said stays, as is shown in Fig. 8.

Said hooks are pivoted to the lowermost links of the upper memcers 27 and are ad apted to engage a link of the lower meinher of the stay, asshown. The rings 30servc to lock the hooks 29 inoperative position. Said hooks may he released by sliding the rings upv beyond the ends of said hooks, so that the hooks may swing so as to release the lower meml: ers of the stays, right in Fig. 7. Obviously when the stays at both sides of the car are operative the carbody is held in its normal or horizontal position, as shown in Fig. 8, but ly releasing the stays at either side the car-l". ody may i e tilted toward the opposite side of the car.

31 32 indicatethe train-pipes, which, as 8 and 9, are arranged at gitudlnally -thereof. Said train pipes are arranged to t e coupled up by couplings 33 34, as shown in Fig. 10, so that all the train-pipes at the same side of the car are in communication with one another.

35 is a diagrammatic representation of 'ia lo'connptive which is prov ded with C01'l1' *pres'se'd-airaupplying mechanism 36, connected by a pipe 37 with a cook 38, the latter he: ing connected by branch pipes 39 4,0 with the train-pipes 33 34, respectively, as shown in Fig. 10. The cook 38 is a three-way cock arranged so that air may be admitted t9 either train-pipe alone. The cook 38' is e constructed as to provide also for admitting air to both train-pipes at the same time, as

as shown at the sition.

or cars were dumped, thereby pulling down the elevated side edges of the'carebodies and restoring them to their former position, the

stays at the opposite side serving to stop the car-bodies when they reach their normal po- The disconnected stays are then connected, and the car-bodies are in readiness for anotherload. If it be desired to dump onlypa' part of the cars at the same time, the cars which are not to be dumped are c'ut out by closing the cut-out valves 44 or 47, as the case may be. Again, if it be desired to dump certain cars at one side and other cars at the other side the stays are properly arranged and the cutout valves corresponding adjusted. Air is then admitted to both train' pipes at the same time, when the cars will be dumped accordingly. To restore the carbodies when so dumped, the cut-out valves are reversed and air again admitted to both train-pipes. In practice the valve 88. is first set to properly direct the air-supply, and the air-pressure is then controlled by operating the valve 37; In this manner the air-pressure may be a plied, released, or,otherwise controlled at cab. While -I have described specifically the embodiment of my invention illustrated'in the accompanying drawings, Iwish it to be understood that my invention is not restrict- -ed to the details of the construction shown and described, except in so 'far as they are particularly clairne but includes genericallyrthe subject-matter of the broader claims.
